As Steve pointed out recently, Google has a phone/voice-based front-end to some of their search services. But did you also know that you can send an SMS text message to G-O-O-G-L-E (466453)? The best way to interact with it is to send a message like this:

This will return all business results for “pizza” in the 97211 zip code. You’ll get a text message (or two, for lots of listings) back in a few seconds which will include name, address, telephone number, etc. After sending a couple zip-coded messages, Google will tell you that you’ve set your geographic preference and subsequent messages don’t need the zip code preface.

Anyone know if this works with the new cell-tower-triangulation that’s been bandied about?
